To all whom it may cancer-n:

Be it known that 1, JOHN DICKENS MACK- INTOSH, a British subject,residing at Openshaw, city of Manchester, county of Lancaster, England,have invented certain new and useful Improvements in Socks for Boots andShoes, of which the following is a specification.

This invention relates to improvements in socks or insoles for boots andshoes.

The sock or insole is then saturated with a solution of capsicin made upas follows Capsicin 1 oz. Methylated spirit oz. fluid. Water 29 oz.fluid.

The sock or insole is then dried in warm room or chamber and afterdrying is sprayed with a solution of oil of Wintergreen (methylsalicylate) and castor oil in methylated spirit made up in the followingproportionsz- Oil of Wintergreen l fluid oz. Castor oil 1 fluid oz.Methylated spirit 8 fluid oz.

'][he-ad dition of the castor oil prevents the 011 of Wintergreenvolatilizing too readily.

After spraying with the oil of wintergreen solution is dried at atemperature of about 120 F., and finally pressed.

Instead of treating the sock after it has been made up the material maybe first treated and then made into a sock.

A sock or insole so treated will have thermal properties and assist inkeeping the feet of the wearer Warm in cold Weather.
